Abstract
The utility model discloses a mud valve plate with good sealing performance. The mud valve plate with the good sealing performance comprises a valve plate. An annular protrusion is arranged on the periphery of the lower surface of the valve plate, and nylon strengthening rubber is covered on the side surface and the annular protrusion of the valve plate. A guiding drum is connected with the center of the upper surface of the valve plate, and a guiding rod is installed in the guiding drum in a sliding mode. An outer edge is arranged on an end portion of the guiding rod, springs are arranged between the end face of the guiding rod and the valve plate, and the springs are respectively contacted with the guiding rod in an elastic mode. A rubber ring is sleeved on the guiding rod and is placed between the outer edge of the guiding rod and the guiding drum. Due to the fact that the rubber ring is sleeved on the guiding rod, the sealing performance of the mud valve plate is improved. The mud valve plate with the good sealing performance is simple in structure, convenient to manufacture and use, small in resistance coefficient and friction, high in reliability and good in practicability.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of valve plate of sludge valve of good airproof performance.
Background technique
Soil discharging valve has another name called and covers valve, be usually used in the deposition tank of city water factory, sewage treatment works at the bottom of discharging mud use.The Applicable media of soil discharging valve is native sewage water, and the temperature of medium generally should be less than 50 ℃, and its operating depth is less than 10 meters.Soil discharging valve also is used for water treatment plant as the mud and the waste water that discharge in the pond.Soil discharging valve is corner-shape structure, and inner nylon reinforcing rubber barrier film can be for long-term soil discharging valve.The valve plate of sludge valve of prior art is unreasonable owing to relating to, poor sealing.
The model utility content
The utility model purpose is exactly in order to make up the defective of prior art, a kind of valve plate of sludge valve of good airproof performance to be provided.
The utility model is achieved through the following technical solutions:
A kind of valve plate of sludge valve of good airproof performance, comprise a valve plate, described valve plate lower surface edge is provided with annular protrusion, and be coated with nylon on its side and annular protrusion and strengthen rubber, described valve plate upper face center is provided with and is connected with guide, is slidably fitted with guide rod in described guide, described guide rod end is provided with the outer, be provided with spring and equal Elastic Contact with it between its end face and described valve plate, on described guide rod, cover has rubber ring, and described rubber ring is between guide rod outer and guide.
The utility model has the advantages that: the utility model overlaps on guide rod rubber ring, has increased the sealing of valve plate of sludge valve, simple in structure, makes easy to usely, and resistance coefficient is little, rubs little, and reliability is high, and is practical.
